Science

The U.S. Fish and Wildlife Service has a long tradition of scientific excellence and always uses the best-available science to inform its work to conserve fish, wildlife, plants, and their habitat for the benefit of the American public.

National Wildlife Refuges

Where Wildlife Comes First

Created in 1903 by President Theodore Roosevelt, today's National Wildlife Refuge System protects habitats and wildlife across the country, from the Alaskan tundra to subtropical wetlands. Managed by the U.S. Fish and Wildlife Service, the Refuge System's 560-plus refuges cover more than 150 million acres and protect nearly 1,400 species of birds, mammals, reptiles, amphibians, and fish.

While national wildlife refuges were created to protect wildlife, they are for people too. Refuges are ideal places for people of all ages to explore and connect with the natural world. We invite you to learn more about and visit the national wildlife refuges and wetland management districts in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.

Ecological Services

The Mountain-Prairie Region's Office of Ecological Services (ES) works to restore and protect healthy populations of fish, wildlife, and plants and the environments upon which they depend. Using the best available science, ES personnel work with Federal, State, Tribal, local, and non-profit stakeholders, as well as private land owners, to avoid, minimize, and mitigate threats to our Nation's natural resources.

Migratory Birds

Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. The Migratory Bird Program is responsible for maintaining healthy migratory bird populations for the benefit of the American people.

Fish and Aquatic Conservation

The U.S. Fish & Wildlife Service Fish and Aquatic Conservation Program in the Mountain-Prairie Region helps conserve, protect, and enhance aquatic resources and provides economically valuable recreational fishing to anglers across the country. The program comprises 12 National Fish Hatcheries.

External Affairs

External Affairs staff in the Mountain-Prairie Region of the U.S. Fish and Wildlife Service provides support to the regional office and field stations to communicate and faciliate information about the Service's programs to the public, media, Congress, Tribes, partners, and other stakeholders in the 8-state region.

Additional hearings will take place on November 20 in Albuquerque and November 22 in Sacramento. Each will include a short informational presentation. The Service has also added a public information meeting and hearing in Pinetop, Arizona, on December 3. The hearings are part of the Service’s continuing efforts to provide an open, comprehensive public process for the two proposed wolf rules and will provide the public a forum by which to register their views.

As a result of delays caused by the lapse in federal appropriations, the comment period deadlines were extended until December 17 to allow this and two other hearings to take place within the public comment periods on the proposed rules.
